More of a WWYD. Cannot agree on surname for our soon to be born child. Namechanged for this.
DP doesn't believe in marriage- fair enough. We have different surnames.
His surname- Smith- is the same as both his parents, paternal grandfather etc.).
My surname- Jones- is my ex DP's name. I changed it over a decade ago by deedpoll to match my DD. This has been my surname my whole adult life nearly. It's on all my documents and I don't go by my maiden name at all. DD has a very involved father and I can't change her surname. I also don't want to have a different surname to her.
My maiden name (Brown) is my father's name who I am no contact with. My mother has a totally different surname (Green).
I want to double-barrell Smith-Jones. DP wants just Smith. He hates double-barrell so said it can't be both names. I said fine, just Jones then. He is very much against that as it's not my 'real' name and it is essentially another man's name (though aren't they all?). He said if we don't go for Smith, we should go for Brown. But that's not my name and I've no intention to reverting to it. He said we should go for Green then, but it's the same issue. I don't want to have a surname that is not the same (or partly the same in the case of a double barrell) with either of my children, but we totally disagree.
The not getting married is not an issue, although I happily would, but I am not giving my child just DP's name if it's not also partly my surname (I'd become a Smith-Jones if we married- DC would then just be Smith). AIBU? Which name would you pick?
